Housing tenure, residential moves and children’s educational performance in Accra, Ghana
Research has shown that non-conventional factors like housing and residential experiences during childhood have impacts on children’s success. Given the critical importance of human capital accumulation in Ghana, it is significant from policy standpoint to recognise factors and mechanisms that are relevant to the next generation’s educational performance. This paper attempts to identify the impacts of housing tenure and residential moves on the educational performance of children. The research focused on Junior Secondary School (JSS) leavers in Accra. Chronological information of the Pupils during childhood on residential moves and their educational performance between the ages of 12- 17 (JSS level) was collected. The results of the analysis indicate large disparities in educational outcomes between children with different housing tenures and strong residential mobility experiences. Even after taking into consideration a set of rich endogenous factors, a positive home ownership effect and a negative residential moves effect remain with significant magnitudes
Spin gating electrical current
We use an aluminium single electron transistor with a magnetic gate to
directly quantify the chemical potential anisotropy of GaMnAs materials.
Uniaxial and cubic contributions to the chemical potential anisotropy are
determined from field rotation experiments. In performing magnetic field sweeps
we observe additional isotropic magnetic field dependence of the chemical
potential which shows a non-monotonic behavior. The observed effects are
explained by calculations based on the kinetic
exchange model of ferromagnetism in GaMnAs. Our device inverts the conventional
approach for constructing spin transistors: instead of spin-transport
controlled by ordinary gates we spin-gate ordinary charge transport.Comment: 5 pages, 4 figure
